I-deas Workflows in NX

1. I-deas Workflows in NX Presented by Mike Morse Technical Marketing

2. I-deas Workflows in NX 6 • Question: • How many of my familiar I-deas modeling, assembly, and PMI functions and workflows are available in NX? • Answer: • Question: • Do I have to abandon my I-deas “Best Practices” and learn a complete new set for NX? • Answer:

3. I-deas Workflows in NX 6 • I-deas ≠ NX • NX ≠ I-deas • Major Differences: • Interface • Fixed vs. Flexible • Units • SI Units vs. Metric / English • History Representation • “Bushy” vs. “Timestamp” • “Multiple Parts on Workbench” • Yes or No? • Parasolid Kernel • Partition/Boolean yielding multiple solids • Drafting • External vs. Integrated • Data Management • TDM vs. Teamcenter vs. “Native”

4. I-deas Workflows in NX 6 • I-deas = NX • Most I-deas Workflows have Logical Equivalents in NX • Major Similarities: • “Sketch – Constrain – Extrude” • Hybrid Open & Closed Part Modeling • Freeform Surfacing • Drafting / Blending / Shelling • Copy / Paste / Replace / Reuse Features • Cross-over Modeling Features: • Sketcher; V-Sweep; Emboss • Cross-over Assembly Features • Assy.

7. New Part • I-deas New Part includes Absolute CSys • Units are not an issue • (SI units used internally) • NX New Part based on Template “Seed Part” • Metric vs. English must be specified • Different Seed Parts for Different Applications • Model vs. Assembly vs. Drawing vs. NASTRAN… • Modeling may be done in ANY units • Analysis -> Units • I-deas may have multiple “Parts” on “Workbench” • NX may have multiple “Solids/Sheets” in one part; • Use File -> Import -> Part to add parts together • Use Assembly to display multiple parts at once • Use Window to switch between loaded parts

8. Part Navigator • “One Stop” Feature Information / Editing Panel • Columns show Feature Name, Type, Modified Date, Alerts, Reference Sets, etc. • Use to Rename / Group / Suppress / Show – Hide / Reorder / Delete Features • Includes More than Feature Information: • Model Views, Cameras, Expressions, PMI, Drafting Sheets • “Details” Panel for Dimension Values • “Dependencies” Panel for Parent / Child Relations • Two Basic Display Modes: • “Timestamp” • Like I-deas “Linear” History Tree • Most Commonly Used • “Design View” • Similar to I-deas “Bushy” History Tree • Useful for Isolating Tool Features • Do you really need a “bushy” history? • “Rollback” and Insert Features anywhere. • “Drag and Drop” to reorder features. • Filter to Quickly Find Features

9. Typical Modeling Workflow Design Target Body Sketch Section Design Tool Body Relative Datum or Datum CSYS Boolean Operation

10. Datums • “WCS” – Unique, Dynamic “Work Coordinate System” • Optional Method for Positioning • Datum Axes / Planes / Coordinate Systems • Very Similar to I-deas • Many options for Datum Planes • Similar options for Datum Coordinate System • Representation equal to I-deas (planes, vectors, point) • Offset CSYS may be translated/rotated or vice versa • Use Datum CSYS as first feature for modeling • No Need for Reference Curves • Sketches persist as required • Optional Sketch Reference Curves do not participate in feature creation (Extrude, Revolve) • Sketch on Path orientation options similar to I-deas

11. 2D Sketch • Unique Sketcher Task • Enhanced with I-deas input • Sketch on Plane or Path • Path must be used for V-Sweep • Horizontal / Vertical Reference • Curves change color when partly/fully/over constrained • May snap to grid • May create Reference sketch curves • “Construction” curves, not for feature creation • Degree of Freedom arrows vs. Show Free • Drag curves or Animate Dimensions to show free motion • Can’t Drag Dimensions • Automatic and Inferred Constraints

12. 2D Sketch cont. • Curve creation very like I-deas: • Profiles, lines, arcs, circles, conic, splines, rectangles… • Intersect, mirror, offset, trim, extend, make corner, fillet… • No Need to “Focus” • Select edges directly • Projection to sketch plane is possible • Dimension values from Global Expressions • Curves may be grouped for easy reuse • “Fixed” text height; automatic orientation to view • Automatic reorientation of sketch plane to view • Local or Absolute origin • Sketches may or may not be absorbed – your choice • Sketch Plane / Path may be respecified

13. Selection Intent • Concept Adopted from I-deas • Selection Intent “Toolbar” • “Snap Points” during sketching / positioning • Selection “Filter” (Solid; Face; Edge; Curve; etc.) • Selection Continuity (Single; Connected; Tangent; All) • Stop at Intersection; Follow Fillet • Select All / Deselect All • Selection by Group Name • “Quick Pick…” vs. “Reconsider” • Prioritizes selection options • Bodies vs. Features e.g.

14. 3D Curves • Many options similar to I-deas: • Lines, Arcs, Splines, Conics, Polygons, Text • Optional Associativity • Intersect, Draw on Surface, Offset On Surface, Bridge, Circular Blend, Project, Cross- Section, Wrap, Unwrap, Helix, Law Curve, etc. • Extract, Mirror, Project, Combine Projection • Dynamic Spline Editing • Thru Points / Control Points / Degree • Enhanced spline curvature continuity (G0, G1, G2)

15. 3D Shapes – Solids & Primitives • Solid = Closed Part • Based on Parasolids Kernel • Created from Closed Section(s) • Extrude / Revolve / Sweep / V-Sweep / Tube • Offset during creation of Extrude/Revolve simplifies sketch requirements • Created from “Primitives” (Design Features) • Block, Cylinder, Cone, Sphere • Quick Parametric Creation of Common Shapes • Hole, Boss, Pocket, Pad, Slot, Groove • Some Features Recognized by CAM • Created by “Sewing” Sheets Together • “Unsew” to Convert Solid to Sheets

17. Boolean Operations • Solids: • Unite / Subtract / Intersect / Split / Assembly Cut • Sheets: • Sew / Emboss Sheet / Trim Sheet or Body / Trim-Extend / Patch • Boolean may be specified during Feature Creation • If so, Boolean type may be changed later • Solids– Same as I-deas; except: • Original “Target” and/or “Tool(s)” may be Retained • Not Automatically Absorbed like I-deas • Sheets • May be Cut or Intersected by solids • May be “Embossed” by Solids (like Join w/Material Side) • Solids may be Trimmed or “Patched” by Sheets • Direction Toggles - Results like Material Side • Sheets may be Trimmed by Other Sheets • “Make Corner” Option Available w/Direction Toggles • May be “Sewn” Together into Larger Sheet or Solid • May be “Unsewn” to Give Sheets From a Solid

30. I-deas Workflows in NX 6 • Question: • How many of my familiar I-deas modeling, assembly, and PMI functions and workflows are available in NX? • Answer: • Lots. (More than you might think.) • Question: • Do I have to abandon my I-deas “Best Practices” and learn a complete new set for NX? • Answer: • NO! Best Practices can migrate as well as geometry.
